Melania Trump returned to the White House on Saturday after a near week-long hospital stay following kidney treatment, a duration which raised questions about whether the First Lady’s condition may have been more complicated than initially revealed.

Her spokeswoman Stephanie Grisham has declined to release additional details, citing Mrs Trump’s right to privacy.

“The First Lady returned home to the White House this morning,” Grisham said in a statement emailed on Saturday.

“She is resting comfortably and remains in high spirits. Our office has received thousands of calls and emails wishing Mrs Trump well and we thank everyone who has taken the time to reach out.”

Mrs Trump had been at Walter Reed National Military Medical Centre near Washington since Monday when she underwent an embolisation procedure to treat an unspecified kidney condition which the White House described as benign.

Our great First Lady is doing really well. Will be leaving hospital in 2 or 3 days. Thank you for so much love and support!

Word of the hospitalisation came as a surprise because there was no indication in numerous public appearances in recent weeks that Mrs Trump had been ailing.

First ladies are under no obligation to make their medical histories public. A week before undergoing the procedure, a beaming Mrs Trump presided over an announcement ceremony in the White House Rose Garden to introduce her Be Best public awareness campaign to help teach kindness to children.

Ms Grisham said on Monday that the procedure was “successful”, there were no complications and that Mrs Trump would probably remain hospitalised for “the duration of the week”.

The president then tweeted on Tuesday that his wife would be released in “two or three” days, but Thursday and Friday passed without word from the White House on her whereabouts.

A sincere thank you to Walter Reed Medical Unit @WRBethesda & to all who have send good wishes & prayers! I am feeling great & look forward to getting back home @WhiteHouse soon.
